Table 3

The correlation between the commercial formulation of glyphosate (Roundup 41% SL, Bayer AG, Leverkusen, Germany) and damages of grass carp gills (Ctenopharyngodon idella).

Tissue damages	Concentration (mL L^−1)
	0	50	100	150
Lamellar fusion	–	++	+++	+++
Lamellar aneurism	–	–	++	+++
Epithelial hypertrophy	–	+++	++++	+++
Leukocyte infiltration	–	–	++	++++
Basal Hyperplasia	–	++	++	+++
Distal hyperplasia	–	++	+++	+++
Necrosis	–	–	++	++++

Note. All concentrations are nominal. Also, none (–), mild (++), moderate (+++), and severe (++++) of tissue damage.
